DRINKING-CUP.

I Specification of Letters Patent.

REISSUED Patented July 27,1915.

To all whom it may concern Be. it known that I, HENRY B. CooLEY," acitizen of the United States, residing at Kensington, in the county ofHartford,;'

State of Connecticut, have invented a new and Improved'Drinking-Cup,"ofwhich the following is a specification. 7

My invention relates more especially to that class of drinking cups thatare made from paper or other light material and that are intended forindividual use, and an object of my invention,among others, is ,toprovide a cup of this class with its lip thickened to provide sufficientrigidity to resist collapse under weightof the contents.

One form of cup embodying my invention, and in the construction and useof which the objects herein set out, as well as others, may be attained,is illustrated in the accompanying drawings, in which- Figure 1 is aview in elevation of one side of a cup embodying my invention. Fig. 2 isa view of the opposite side of the cup. Fig. 3 is afview in lengthwisesection on plane denoted by dotted line 3-3 of Fig. 1,

the cup being shown as partially opened to illustrate its form when inuse for drinking purposes, the thickness of the material beingexaggerated. Fig. 4 is a view in sectionon plane denoted by dotted linefrf: of Fig. 1, the cup having the same form as in Fig. 3 and thethickness of the material being we aggerated.

My 'nvention' appertains to the class of sanitary drinking cups composedof paper or other thin material folded to provide a fiat structure, butthe back and front walls of which are separated, especially at the top,v

when required for drinking purposes.

Heretofore the lips or drink edges of the cups have been composed of asingle piece of thin material, as paper, with insufficient rigidity toresist collapse from the weight of the contents, with a result that suchcontents are liable to be spilled upon the personusing the cup, and thissingle thickness also presenting a sharp edge liable to cut the flesh.My improved cup is constructed to overcome these objections and the lipor drinking edge is sufficiently stiff to resist the weight of thecontents and prevent collapse, such cup being illustrated in theaccompanying drawings, in which the numeral 5 indicates what I term thefront flap of the cup, this being the flap, the upper or drinking Edgeof: which is presented to the li i drinking, and the numeral 6 denotesthe back flap. These two flaps are preferably formed of a single pieceof material folded i 1 at the bottom edge 7 and the back flap ispreferably cut away as at-"8 'toreinove such part as would be liable tomake contact with the nose of the person using the cup.

' The back flap 6 is provided with longitudinal folded edges 9 adaptedto be folded over the front flap .5 to secure the two flaps together andclose the seam at the edges of said flaps.

The upper edge of the front flap is provided with a reinforcing orstiffening piece manner, in apreferred form and asshown herein thisbeing overturned from the flap 5. In order to increase the rigidity ofthis stiffening piece 10, by preventing a creeping 0 10 that may beconstructed 1n any desired movement crosswise of the cup, thisstiifening piece at its ends is located underneath the folds 9 andsecurely fastened thereunder. In the preferredform of construction bothsides of thestiifening piece are provided with an adhesive at the pointsoverlaid by the folds 9, so that the stiffening piece at this point issecured firmly against the outer surface of the front flap 5 and thefolds 9 are securely held, against the outer surface of the stiffeningpiece. Preferably the entire under surface of the latter is providedwith an adhesive so that it is securely fastened against the outersurface of the flap 5. In order to provide the greatest rigidity at thepoint of greatest strain the lip 10 is gradually widened from its endsto the center, at which latterpoint the greatest pressure occurs.

v A cup constructed as :above described is found'to, possess all of therequirements for the use to which the cup isintended to be put, and theupper or-drinking edge is'sufliupper edge thereof and extendingthereacross, and means overlapping each end of said stiffening piece tosecure it in place.

2. A drinking cup including a front and back flap, lengthwise folds forsecuring said flaps to ether, and a stiffening piece secured to the.rinking edge of the cup and with its ends underlying said flaps andsecured in place thereby.

3. A drinking cup composed of a front and a back flap, lengthwise foldsfor securing said flaps together, and a stiffening piece overturned onthe outside of the drinking edge of said cup and extending underneathsaid folds and provided with an adhesive on its opposite sides to secureit to the flap and to secure the lengthwise folds thereto.

4. A drinking cup consisting of a front 1,1&8,149

and back flap, a stiffening piece secured to the upper edge of one ofsaid flaps and 20 gradually increasing in width from its ends to itscenter, and folds at the edges of the cup engaging said stiffening pieceto secure it in place.

5. A drinking cup including a front flap and a back flap, the latterbeing folded lengthwise at its edges onto the front face i of the frontflap, and a stiffening piece folded over from the upper edge of thefronti flap and having its ends underlying and se- '30 cured by thefolded edges of the back flap. if
